Fuf, I had the Eden 215XLT driven with a Eden WT550 head, (they were stolen back in Nov. of last year). I'm in a loud, 6 pcs., country/rock group and I've got P.A. support most of the time. Were playin' everything from animal clubs to outside fair dates. This cab was used as a stand-alone.
All I can say is the 215XLT was great, huge lows, filled the stage, and projection like few other cabs can match. It's only down side is it hasn't got a fast response like 12's or 10's....but it was the fastest 215 cab I've played through to date. It was also the best sounding 215 I've played through.
I'm now using my old GK800 head into a Eden 212XLT cabinet. I "MUCH" prefer the 212XLT. It's lows are very near what I had from the 215XLT, projection is about the same (according to our sound man), but it seems to cut through the band alittle better. It has a much faster response, lighter in weight, and very easy to move around.
When I can afford to rebuild my rig it'll probably be either....#1.... two 212XLT'S with a WT 550 or WT 405 head....or....#2....A 212XLT with a 210XST and a WT550 head.
